1 BLZPTS-1 NOVEMBER 19, 2013 TS350 TS752 BLPS PRESSURE AND TEMPERATURE SENSORS for use with the BURNERLOGIX Burner Management System and PPC4000 Series Fuel/Air Ratio Controller DESCRIPTION The BLPS, TS350 and TS752 Series of pressure and temperature sensors are designed for use with the PPC4000 Fuel Air Ratio Controller and BurnerLogix Burner Management System with Integrated Boiler Control. The pressure sensors (P/N BLPS-x) utilize a solid state pressure transducer to indicate steam pressure. The temperature sensors (P/N TS350-x and TS752-x) utilize a platinum, positive temperature coefficient sensing element to provide indication of water temperature, stack temperature, boiler water temperature of a steam boiler, and outdoor air temperature. The pressure sensors have a maximum overpressure specification of 200% Full Scale Output and 800% Burst. The pressure sensors are equipped with a 1/4" NPT male fitting. The Immersion Style Temperature Sensors have a 1/2" NPT mounting for the 2", 4" and 8" thermowell probe. The pressure and temperature sensors provide a 4-20 ma control signal over their respective stated ranges to the PPC4000 and BurnerLogix Control systems. No setting or calibration is required for either type of sensor. The PPC4000 and BurnerLogix Control systems perform continuous safety checks on the operation of all pressure and temperature sensors to insure their safe and proper operation (e.g. under range, over range, open wiring, etc.). WARNING: The PPC4000 Fuel Air ratio Controller and BurnerLogix Control System must only be used with the approved pressure and temperature sensors. (e.g.: BLPS-15, TS350-4, etc.). Do not use with any other types of pressure or temperature sensors. UL approval requires these sensors. 1

Failure to follow them could result in a hazardous or dangerous condition. 2. Insure that the range of the selected sensor is appropriate for the application. Note: A general rule to follow when selecting the sensor range is that the expected value of the monitored pressure or sensor should fall between 40-70% of the upper range of the sensor. For example, a steam boiler maintains 20 lbs. pressure, select the BLPS-30 Pressure Sensor, with a 0-30 PSIG range 3. The sensors must be located where the ambient temperature will not exceed the maximum ambient operating temperature specified for the sensor. 4. Insure that the pressure range programmed on the BurnerLogix Boiler Room Control matches the installed pressure sensor. Refer to Bulletin BLZ Do not mount any of the sensors where they could be used as a footstep. 6. Installation must be performed by a trained, experienced flame safeguard technician. 4

5 WARNING: The electro-mechanical high steam limit and/or high hot water temperature limit MUST REMAIN in the running interlock circuit of the flame safeguard control. MOUNTING PRESSURE SENSORS Note: Refer to Figure The steam pressure sensors (BLPS-15, -25, -30, -200, -300) provide a 1/4 NPT male fitting for connection to the steam header. Included is a 1/4 coupling. 2. Make sure the boiler is shut down and zero steam pressure exists in the boiler vessel. 3. Disconnect power to the boiler controller so the boiler cannot sequence during installation of the steam pressure sensor. 4. Always mount the steam pressure sensor above the water line of the boiler. 5. Locate the pressure sensors where the ambient temperature will not exceed 185F FIGURE 4. STEAM PRESSURE OR HOT WATER SENSOR ELECTRO-MECHANICAL HIGH LIMIT (STEAM OR WATER) 6. Although the unit can withstand substantial vibration without damage or significant output effects, it is good practice to mount the pressure sensor where there is minimum vibration. 7. A steam trap (siphon loop) must be connected between the boiler and the pressure sensor to prevent boiler scale and corrosive vapors from affecting the pressure sensor element. 8. Use only a small amount of pipe compound to seal the connection joints. Excess pipe compound may clog the fitting and prevent proper operation of the sensor. 9. Make all pipe connections in accordance with approved standards. 10. When tightening the sensor, apply a wrench to the hex flats located just above the pressure fitting. DO NOT tighten by using a pipe wrench on the housing. Do not tighten the pressure sensor by hand. MOUNTING TEMPERATURE SENSORS The immersion style temperature sensors have a ½" NPT mounting for the 2", 4" and 8" thermowell probes, and a ½" conduit fitting. HOT WATER Note: Refer to Figure 4 1. Disconnect power to the boiler controller so the boiler cannot sequence during installation of the hot water temperature sensor. 2. The thermowell must be mounted where it is always exposed to the circulation of the hot water 3. If the water system is full, drain the system below the point where the thermowell will be installed. 4. Tap an appropriate size fitting. (2", 4" and 8" thermowell have ½"NPT fitting). 5. Insert the appropriate thermowell (2", 4", or 8") and tighten. 6. Fill the system to check for leakage. 5

6 LEAD/LAG OPERATION: When two hot water boilers are set-up for lead/lag operation, a hot water temperature sensor must be installed for each boiler. STANDBY WATER TEMPERATURE 1. Disconnect power to the boiler controller so the boiler cannot sequence during installation of the standby temperature sensor. WARNING: Location of the temperature sensor to monitor boiler water temperature of a steam boiler is critical. The sensor should be mounted where it is always exposed to the circulation of the boiler water, not too close to a hot or cold inlet or steam coil. Consult the boiler manufacturer for guidance on the sensor location. 2. The thermowell must be mounted where it is always exposed to the circulation of the hot water. 3. If the water system is full, drain the system below the point where the thermowell will be installed. 4. Tap an appropriate size fitting (2", 4" and 8" thermowells have 1/2" NPT fitting). 5. Insert the appropriate thermowell (2", 4", or 8") and tighten. STACK TEMPERATURE 1. Use the existing well connection for the stack temperature sensor if provided by the boiler manufacturer. 2. If no well connection is provided, select an appropriate location for mounting the temperature sensor. Preferably as close to the boiler outlet as possible. OUTDOOR AIR TEMPERATURE 1. The outdoor air temperature sensor should be mounted on the outside of the building where it will be exposed to representative air temperature, but not to direct sunlight. A sun shield may be required. 2. Mount the temperature sensor high enough so it cannot be covered with snow, leaves, or other debris, or be tampered with. Vents from the building should be avoided. 6
